For about a week now my website displays these errors when somebody navigates to it:

Warning: mysql_query(): MySQL server has gone away in /storage/h2/613/637613/public_html/wp-includes/wp-db.php on line 1879Warning: mysql_query(): Error reading result set's header in /storage/h2/613/637613/public_html/wp-includes/wp-db.php on line 1879Warning: mysql_query(): MySQL server has gone away in /storage/h2/613/637613/public_html/wp-includes/wp-db.php on line 840Warning: mysql_query(): Error reading result set's header in /storage/h2/613/637613/public_html/wp-includes/wp-db.php on line 840

I was told by someone yesterday that this means there is something wrong with my code, but I haven't changed my code recently. Any help is appreciated.

It does seem to be working now. I tried clearing my cache and that did the trick. It's strange because I tried doing the same thing last week when it started, but it didn't work, and others were experiencing the same issues. Glad it's back up though!
